Texas, the nation's top oil-producing state, saw the biggest diesel spike in the country in the past week — a cost of the Iran war.

Why it matters: The fuel-price increase is slamming states that could decide Senate control in November, a potential headache for Republicans defending their majority.

• Affordability was already Democrats' central midterm message, and now the cost of President Trump's unpopular war is on display at the pump.

State of play: Just 29% of Americans approve of the strikes, and two-thirds — including 44% of Republicans — expect gas prices to keep rising, according to a Reuters/Ipsos poll conducted through Monday.

Zoom in: Gas prices were about $2.74 per gallon a week ago in Texas.

• The average price of a regular gallon of gas in Texas was over $3.20 as of Tuesday, per AAA.
• Average prices were higher in North Texas, with an average around $3.36, just below the national average.

By the numbers: Three of the top four weekly jumps in diesel prices hit key midterm Senate races: Texas (+111.6¢), North Carolina (+110.5¢) and Georgia (+107.9¢), according to GasBuddy's Patrick De Haan.

• Regular gasoline spikes also hit battlegrounds. Ohio and Michigan tied for the third-largest jumps at 55 cents.
• A month ago, just nine states averaged gas prices above $3 per gallon, according to GasBuddy. Now that number is 48.

Zoom out: The national average for regular gasoline hit $3.55 on Tuesday, up 61 cents from a month ago, according to GasBuddy.

Between the lines: Oil is the invisible cost inside nearly everything Americans buy. It ships the goods, makes the plastics, feeds the fertilizer and fuels the flights.

What they're saying: Trump touted low gas prices in his State of the Union just days before launching strikes, on cost-of-living concerns.

• On Sunday, he dismissed the fuel price surge on Truth Social, calling it a "very small price to pay for U.S.A., and World, Safety and Peace.
• Meanwhile, Democrats are hammering him on cost-of-living concerns.

The bottom line: The eight months until the November election could be enough time to put pump-price shock in the rearview mirror, De Haan says.

• But if Trump "doesn't reverse course, he certainly could start to bring about a situation that will be more memorable to Americans ahead of the midterms."

Dallas-Fort Worth will receive a $10 million grant Congress approved this month for public transit improvements ahead of the World Cup.

Why it matters: AT&T Stadium will host more matches than any other venue — in a city known for eschewing public transportation.

The big picture: The transportation grant is the second largest allocation among the World Cup's U.S. host cities, just shy of the New York-Jersey City-Newark metro's $10.3 million.

How it works: Host cities will be able to request reimbursement for public transportation planning leading up to the World Cup and operating expenses during the tournament, after subtracting revenue collected through fares.

• The money can only be used for regularly scheduled, shared-ride transportation that is open to the general public — not for charter buses, transportation for World Cup fans only or courtesy shuttles for patrons of specific establishments, per the Federal Transit Administration.

What they're doing: The Trinity Railway Express will run every 30 minutes from downtown Fort Worth and Dallas to Centreport Station on match days. From there, buses will take fans to a station created outside the stadium.

Speaking of the World Cup, you won't need a ticket to get into the FIFA Fan Festival at Dos Equis Pavilion in Fair Park this summer.

Why it matters: The festival might be a cheaper option for locals who don't care to splurge on World Cup tickets or commute to Arlington.

State of play: Dallas' FIFA Fan Festival will be open all 34 match days, stretching longer than the 24-day State Fair of Texas. The festival will not be open during the tournament's five rest days.

• Expect matches broadcast on giant screens, skills contests, concerts and other performances, and food from local vendors.
• There will also be an interfaith prayer space, onsite worker support hub and a playground with a mini pitch.

By the numbers: The festival will be able to accommodate around 35,000 fans at any time between Dos Equis Pavilion — formerly known as Starplex Pavilion — and lots 9 and 10, organizers say.

• The amphitheater is going through a $2.5 million renovation to prepare for the festival, including fresh paint, new signage and new turf, per the Dallas Business Journal.

The intrigue: FIFA doesn't honor prior naming rights for its venues and is referring to Dos Equis Pavilion as the Pavilion at Fair Park amphitheater for the fan festival.

Plan your visit: The Fan Festival will open one hour before the first match of the day and close an hour after the last match ends.

• Matches that start at either 10pm or 11pm will not be shown.

North Texas remains abnormally dry even after recent rainfall.

Driving the news: Dallas-Fort Worth drought conditions are likely to improve, according to a monthlong outlook from the U.S. Drought Monitor.

• The eastern part of Collin and Dallas counties are currently experiencing a moderate drought, while the western stretch of the region is experiencing dry conditions.

Flashback: D-FW only recorded 1.3 inches of precipitation last month, more than an inch less than normal, per the National Weather Service.

• January recorded even less — 0.93 inches of precipitation — well below the norm of 2.53 inches for the month.

What's next: Dry conditions are expected to return after a drizzly day. Rain chances are low Thursday through Monday, per the NWS.

• Rainfall is slightly ahead of normal this month with more than 1.7 inches recorded.
